WSUS – Error 80244007 when WSUS client scans for updates

Symptom:

You use Microsoft Windows Server Update Services (WSUS) to deploy software updates to computers that are in your organization. When a WSUS client computer scans for updates on the WSUS server, the following error message is logged in the WindowsUpdate.log file on the client computer:

WS error: <detail><ErrorCode>InvalidParameters</ErrorCode><Message>parameters.InstalledNonLeafUpdateIDs</Message><ID>GUID</ID><Method>http://www.microsoft.com/SoftwareDistribution/Server/ClientWebService/SyncUpdates”</Method></detail>”

*FAILED* [80244007] SyncUpdates_WithRecovery failed

Additionally, the following exception is logged in the SoftwareDistribution.log file on the WSUS server:

ThrowException: actor = http://WSUSServerName:8530/ClientWebService/client.asmx, ID=GUID, ErrorCode=InvalidParameters, Message=parameters.InstalledNonLeafUpdateIDs, Client=Client_ID
